the white house says they didn't have that information. the white house saying they were provided with the best intelligence assessment they were able to share, based on the information they had on hand at that time. but, erin, this is one product of the intelligence community. and it doesn't seem to be all of the intelligence that the u.s. government had on the matter. whether that was shared with anybody else, we don't know. >> right. and finally, elise, why did it take intelligence, then, until last friday, 16 days after the attacks, before they changed the assessment. again, given that news outlets, including our own, reported that it was within 24 hours when several of these crucial things, including the involvement of al qaeda-linked groups was known to intelligence officials? >> well, i mean, that's another good question. i mean, this was in the initial days after the attack. it's clearly a picture -- that was evolving. people in the government fighting terrorism were continuing to gather information that suggested otherwise, and as daniel issa just said, sometimes people in the intelligence community don't know until for sure.
